The wind speed normally increases with height in the layer of air next to the ground. This illustrates the fact that:
A) density decreases with height.
B) friction is present only close to the ground.
C) pressure decreases with height.
D) the lowest part of the atmosphere is turbulent.
E) temperature decreases with height.

Friction between the ground and the air slows down the movement of the air near the surface. As a result, wind speeds closer to the ground are generally slower than wind speeds at higher levels above the ground. This is why wind turbines are commonly placed at high altitude to take advantage of the faster wind speeds.
